Lineage
Polhemus was started by Bill Polhemus as Polhemus Associates in 1964.[3] It was founded in Michigan. Polhemus Associates researched how to track objects' position and orientation in a three-dimensional space.[3]
The company moved to Vermont in 1969, and began focusing on hardware. In 1970, Polhemus worked with Northrop Corporation, and then changed their name to Polhemus Navigation Sciences, and incorporated in Vermont.[3][4][5]
Polhemus developed magnetic tracking for tracking a pilot's helmet for use with a head-up display. Polhemus received Air Force contracts in the early 1970s.[3] It faced financial difficulty by late 1973, and the company or its product rights were sold to the Austin Company, which was a conglomerate based in Cleveland, Ohio.
In 1996 and 1997, Philip G. Cooper was the President of Polhemus.[4][6][7]
In 1996, Polhemus was a subsidiary of Kaiser Aerospace and Electronics.[6]
At one point, it was owned by the McDonnell Douglas company.
Polhemus's corporate name is Alken, Inc.[8][9] Alken, Inc. was incorporated in Vermont in 2002.[10]
